So my poor i9000m went for a faceplant earlier this year and the glass was badly cracked. I continued using it for a while until the amoled started displaying messed up colors and finally turned a harsh shade of green so you could barely see what was on the screen.
I disassembled the phone, and discovered the amoled itself had started to crack. Okay, so dead screen. I ordered one of the replacement amoled that include the frame and buttons (for a few bucks more then only the amoled it seemed like a worthwhile convenience).
I got the replacement today, and carefully reassembled the phone around it. Power on... Samsung logo, cyanogenmod logo, startup animation! Awesome I think to myself! But then the cyanogen animation goes weird colors (as if the display was set to 16 color). Phone boots and looks okay, colors maybe a bit faded. Then the screen timeout hits, so I hit the power button to start up again. This time no Samsung logo, just a small green line at the top. After a while cid appears on the boot animation. In the OS, colors look poor (like it is in 256 color mode), and gradients look horribly jaggy.
If I boot into recovery or download mode, I get a little green line that slowly fades to random pixels across the whole screen. Only if I boot into the OS can I see anything. And still, colors look horrible.
I took the phone apart again, cleaned the connectors carefully, but same thing.
Any thoughts? Did I get a dud screen or does this sound like something else is wrong in the phone?

I found an interesting issue with my 2 years old Touch Diamond 2. Don't know whether someone had the same so I'd like to post here for reference.
Few months ago after a phone drop I found a circle of black pixels on the screen after I (as in the attached image), that didn't react on any actions. So I though those were dead pixels - a lot of them!!! BTW, I dropped the phone many times before that.
The most interesting I found later is that in the last winter, the screen had recovered itself - the "dead" black pixels became lighter and lighter and fully recovered - no traces at all
Last week the similar appeared again - this time 3 areas with black dots - and again, after a phone drop. Thinking about the winter time - I tried putting the phone in a plastic bag and left it in the fridge for a night. As the result the black dots became lighter. So I decided to leave it in the fridge (without battery) for the whole weekend. And as expected - the issue is "fixed" - no traces of "dead" pixels remain Already one week since then, the phone still OK.
Can anyone explain me what is behind the issue and the way it could be fixed as above?
I believe the "dead pixels" are just collapsed layers of the digitizer.
The coldness probably just firms up and separates the layers.
You could also try pulling the layers apart with duct tape.

The "dead pixels" I was about are "on" the inner screen, not the outer. So I think it is more likely a LCD issue rather than digitizer, which is sticked with the outer protection layer as I understand. Am I right?
Exactly the same
mttca,
when I read your post I thought you were talking about my Topaz
I really dont know why or wat is the cause of this type of circle.
Last summer i had the same issue and it disappers after 3 days like you say;
the "dead" black pixels became lighter and lighter and fully recovered - no traces at all
but aprox. two month ago i get the "dead pixels" back, but this time my screen wont recover. This pixels are darker after using for some time the phone and became lighter after some hours without use.
I`am not sure to leave the phone in the fridge.
Circle of Dead Pixels
Hi all, sorry to revive this thread - but the same thing happened to be about 2 months ago.
Got the infamous circle of pixels after dropping the phone - I thought the LCD was damaged, so I bought a new one off ebay and replaced it and it worked great.
Now I've managed to drop the phone again and have an almost identical circle of pixels on the new LCD.
So I'm thinking, does the FRIDGE TECHNIQUE actually work? Should i pull apart the phone and just put the LCD in the fridge overnight? Might even try that with the old LCD as I still have it.
The fridge technique does seem to work. A few months ago I dropped my phone and got the "dead" pixels in random clusters on the screen. They were blue in my case when the background on the screen was white. They went away after a day or so.
With the more recent second drop, they did not go away. They did seem to become lighter over night (phone screen off, thus no heat) and became darker when I used the phone. After waiting 4 days and the blue stuck pixels not going away, I decided to try the fridge technique.
I took out the battery, SIM and SD card and put the phone in the fridge for an hour. After removing the phone and powering it on, I noticed that most of the blue pixels had vanished, but some still remained. The ones that did remain were indeed lighter. I did not put the phone in the fridge again that night. The next day, the blue pixels that had vanished because of the fridge technique had come back, but this time it seemed like they were forming a slightly different pattern. In fact they started forming small vertical lines. I guess that's why it's called a Liquid Crystal Display?
Anyway, this time I decided to put the phone in the fridge over night. So again I took it apart and wrapped it in a plastic bag. The next morning I had a perfectly clear screen - all the stuck blue pixels / line fragments had vanished. A few hours later of me using the phone, two or three adjacent blue pixels appeared.
It has been two days now and the two or the pixels that reappeared turned into a group of about 20, again tending to become small vertical lines. This, however is a small percentage of the stuck pixels originally showing due to the second drop. The rest of the stuck pixels seem to be gone.
My plan is to put the phone in the fridge again over night, hopefully eliminating all stuck pixels for good this time.
P.S. Sorry for the long post, I got a bit carried away

have u kept the phone in the freezer or just fridge ?
happened to me last winter. i thought it's going to be dead soon.... and circle disappeared after 2-3 months without any intervention. no clue, but the screen still works and no dead pixels/circles since
So my Screen broke and I bought a new one so I could replace it, the touch screen/digitizer didn't break though... at first the colors just started washing and fading untill the screen ended up completely dark, I could still use the touch screen and feel when I would unlock it, after a day the phone would not give me any feed back by vibrating or turning the orange light while charging, so I dismantled it using some tips from these videos:
http://www.youtube.com/watch?v=Hhj8Xs9vAyg
http://www.youtube.com/watch?v=hTRXSMQ-GJY&feature=related
After I put everything back together the phone is giving me feedback again and I can notice its charging because of the orange light, but the screen won't turn on. Does any one know if I might need to do something on the software side? like needing to re install anything? or do you think I just got a bad screen?
Update: I just took it apart again and reconnected the ribbons, its back together and the screen still won't turn on.
You have the AMOLED screen and not the LCD?
Did you compare the #'s on the old and new to see you got the right part?
Cables are the same, they look the same, part # and stickers are different...
What are the part numbers on your new and old screen? I just went through the same thing, but I'm fairly sure I got the wrong screen replacement. Will have to look more into it later tonight.
My screen wont turn on at all. I was so excited to get my N1 back in action as well.
So it's my second N6 and another problem. Firts they gave me replacement phone, because back cover became unglued and battery expanded. In this replacement, screen is not even. On white webpage right edge of the screen looks much colder, than the left edge. When on dark background, like grey right edge looks blueish and left edge looks normal. I took it on sevice and they told me this is on feature, not a defect or malfunction. Is there some program/kernel/anything, which can control screen edges seperately ? If I turn adaptive brightnes off and screen on brightnes on highest, the problem is much smaller.
In my first Nexus 6 I had screen that was more bright + yellowish at the bottom and darker + pinkish at top. Shop replaced my phone without complaints.
They sent mine to service, and they told that it's feature. Now they dont't answer my messages and I'm stuck with that defective unit.
Well, I woke up this morning to find that my phone had been stuck on the Google boot logo for at least a few hours. I cursed to myself because I already knew it was going to be burned. I booted my phone and as soon as it got to the MultiROM boot screen, man did I feel it. There was a big fat "Google" right in the middle of the screen. I've had an app I found on the Play Store running for ~8 hours, filling the screen with colors flashing back and forth. It's gotten better and I can't notice it anywhere but the MultiROM boot screen anymore (I tested it with multiple burn-in test apps). I guess it's okay but the the concept of a very expensive phone being burned like that kills me inside. One request, can someone get me an exact image of what the screen looks like when it's turning on so I can invert the colors and hopefully get it gone all the way?
I had some burn in that was bad a while back and this app
Display Tester fixed it up well. I used the burn in fix method with the black and white stripes.
My note 8 is 1 and half years old now. about 2 month ago, it start to have an issue that the screen will become yellow and blurred if turn off the screen and turn on again within 5 seconds. when the screen become yellow, the brightness of the screen will drop, also the text on the screen feels like got a shadow effect. Not related to night mode/blue light filter/google book night mode etc, all tested on/off and no use. and recent month it become even worse, when the phone become hot it will also become dim and yellow. any solutions?
the dim and yellow effect even visible when the phone restart and show the SAMSUNG boot animation. when dial *#0*#, check the color, red looks like orange, green is ok, blue looks like purple...

You need a new screen unfortunately. That's not going to go away it's going to get worse.

I agree! Sounds like the display has developed an issue.
well, it seems so, have to replace the display. but the display actually can show the colors well -- when it's cool, and when you press button to activate the screen after the screen had been off for at least 5 seconds.
if there can be a software solution, disable the dim color mask when the phone is hot, then I can save the money for replace the screen...
